Vibrator Battery Life

How long does your vibrator battery life last? I have a vibrator that runs on batteries that lasts pretty long. But my rechargeable one can't seem to hold a charge. Is it defective, or do other people have this problem?

Mine tend to last a couple of weeks but I never leave the batteries in the toy and I use rechargeable. It has cut down on the cost a lot. There are usually coupons in Sunday papers for the rechargeable as well
